Conceptual design for a re-entrant type fuel channel for supercritical water-cooled nuclear reactors

Samuel, Jeffrey 01 April 2011 (has links)
Current CANDU-type nuclear reactors use a once-through fuel-channel with an annulus gas insulating it from the moderator. The current reference design for a CANDU-type SuperCritical Water-Cooled Reactor (SCWR) is to eliminate the annulus gap and use a ceramic insert to insulate the coolant from the moderator. While such a design may work, alternative fuel-channel design concepts are under development to explore the optimum efficiency of SCWRs. One such alternative approach is called the Re-Entrant fuel-channel. The Re-Entrant fuel-channel consists of three tubes, the inner tube (flow tube), pressure tube and an outer tube. The fuel bundles are placed in the inner tube. An annulus is formed between the flow and pressure tubes, through which the primary coolant flows. A ceramic insulator is placed between the pressure tube and the outer tube. The coolant flows through the annulus receiving heat from the inner tube from one end of the channel to another. At the far end, the flow will reverse direction and enter the inner tube, and hence the fuel-string. At the inlet, the temperature is 350°C for a high-pressure coolant (pressure of 25 MPa), which is just below the pseudocritical point. At the outlet, the temperature is about 625ºC at the same pressure (the pressure drop is small and can be neglected). The objective of this work was to design the Re-Entrant channel and to estimate the heat loss to the moderator for the proposed new fuel-channel design. A numerical model was developed and MATLAB was used to calculate the heat loss from the insulated Re-Entrant fuel-channel along with the temperature profiles and the heat transfer coefficients for a given set of flow, pressure, temperature and power boundary conditions. Thermophysical properties were obtained from NIST REFPROP software. With the results from the numerical model, the design of the Re-Entrant fuelchannel was optimized to improve its efficiency / UOIT

New Entrance Creates the Competition Advantage in Luxury-goods Industry

Hsieh, Yi-chien 26 June 2006 (has links)
Despite of global economic depression, the luxury-goods industry has been thriving in the recent years. Luxury brands build brand images such as fashion, classy, and elegance. In this mature market, especially under the domination of 4 major luxury products groups , it is very difficult for a new luxury brand to survive as a late entry. In this paper, based on First-Mover Advantage Theories(Schnaars, 1986; Lieberman and Montgomery, 1988¡Ketc) and the New Business Model(Hamel, 2000), we develop a structural model to discuss how could a new luxury brand succeed competing with existing brands and go international. Shawnyï, a new French-Taiwanese luxury brand, is taken as our study case. Several important findings are as following: 1. No first-mover advantage is found in luxury-goods industry. What make a successful luxury brand should be business activities such as creative concept of designer and efforts on managing brands. 2. First-movers in luxury-goods industry benefit from their long-history brand images, their new designers also bring their brands new images from time to time to lead the fashion. 3. Fashion industry moves from Europe, through America, into Asia, in the meanwhile melts new concepts and creativity. 4. New luxury brands could reach global market by merging with luxury products groups.

The Research of Competitive Strategy for the New Entrant in Taiwan Semiconductor Packaging Industry

Huang, Ching-Tu 25 July 2001 (has links)
ABSTRACT Following the soaring of worldwide semiconductor industry, the semiconductor industry in Taiwan has been developed a unique industrial characters and carried an evolution. As result, the traditional competitive strategy is no longer sufficient enough to meet the demanding of nowadays semiconductor industry. Same as the evolution of worldwide semiconductor, the development of Taiwan semiconductor industry is fluctuated by Silicon Cycle. The demand is booming in the peak season, which attracts lots of new entrants penetrate the market due to high profit attraction, on the contrary, the demand is declining in business recession with impact of over supply, the existing competitors will aim at the productivity efficiency, cost reduction program as well as enhance of the core competence in order to create the differentiation for the new application product and market mix, hence, the newly emerging market is certainly attracted more rival dealer penetration accordingly. The packaging industry in Taiwan semiconductor¡¦s sorts of specific fields is the most competitive one. The thesis research expects to find out how the new entrants in semiconductor packaging industry take the core competence in the severely competitive market. The study includes: (1) Key Success Factor (KSF) (2) Successful competitive strategies (3) Competitive strategies versus the relation of product and market mix (4) The fine tuning of competitive strategy in company growth. The development of competitive strategy includes (1) The analysis of external environment (2) The analysis of internal factors (3) Strategic alliance (4) The CEO¡¦s leadership and management ability (5) Product road map development (6) Market development. The feedback of performance in the execution of the positioned competitive strategies is continuous in favor to the further adjustment of the strategies. The research finally obtains the findings as the expectation of the thesis research through the methods of the analysis of the characters of semiconductor packaging industry, the developing of competitive strategy and case studies and come out suggestions for future entrant¡¦s reference.

Measuring the vocabulary development of new entrant children : a pilot study.

Hastie, Brent Andrew January 2015 (has links)
For children who are learning to read, it is of the upmost importance that vocabulary knowledge is acquired in a timely fashion. Adequate vocabulary knowledge enables children to comprehend the majority of words in a text and this, in turn, influences reading and overall school success. Children who have delayed vocabulary at the point of school entry may increasingly fall behind their peers as reading demands increase. The identification of these children is necessary, yet despite its importance, vocabulary development is not being assessed in a systematic manner in new entrant classrooms. In this study, five receptive vocabulary tests were piloted with 46 new entrant children from four primary schools in the Christchurch area. The purpose of the study was to determine whether it was possible to develop a procedure that could identify children with delayed vocabulary development in an accurate and economical way. The results suggested that none of the four piloted tests were suitable for screening new entrants. These results highlight the need for a closer look at vocabulary testing at this age level.

Behavior and Strength of Simple and Continuous Span Re-Entrant Composite Slabs

Traver, Thomas Mathew 01 August 2002 (has links)
This study investigates the further development of the commercially available re-entrant steel deck profile. The effects of various embossments and continuous construction are investigated through three Series of composite slab load tests. The test specimens in this study were constructed to simulate actual field construction of composite slabs as part of reinforced concrete structures. The results of this experimental study are analyzed using methods given in the ASCE Standard for the Structural Design of Composite Slabs. Recommended design procedures for the improved re-entrant profile are given and various future profile modifications are suggested. / Master of Science

FLUORINATED RASPBERRY-LIKE PARTICLES FOR SUPERAMPHIPHOBIC COATINGS

Jiang, WEIJIE 21 October 2013 (has links)
Raspberry-like polystyrene particles were fabricated through the covalent linkage of small epoxy-functionalized polystyrene particles (PS-GMA) with large amino-functionalized polystyrene particles (PS-NH2). These covalent bonds yielded more stable and robust particle clusters than would be anticipated from non-covalent interactions. While the structures of these raspberry-like particles provided them with a dual-scale hierarchical roughness and re-entrant sites, they were further functionalized with a fluorinated random copolymer to provide them a low surface tension. The fluorinated random copolymer used to functionalize these raspberry-like particles was poly(glycidyl methacrylate20%)-co-2(perfluorooctyl)ethyl methacrylate80%)25 or P(GMA20%-co-FOEMA80%)25, where the subscript 25 denotes the total number of the respective GMA and FOEMA units, while the subscript 20% and 80% denote the molar fractions of GMA and FOEMA, respectively. The epoxy groups of the GMA units could react with the amino groups of the raspberry-like particles, thus incorporating the fluorinated polymer onto the surfaces of the raspberry-like particles. In addition, the FOEMA component provided the particles with enhanced amphiphobicity. Subsequently, these fluorinated raspberry-like particles were cast onto glass slides to demonstrate their superamphiphobic properties. These coatings exhibited superhydrophobic behavior when they were tested against water droplets. Additionally, the oil-repellency of these coatings was tested against various liquids, including diiodomethane, cooking oil, and hexadecane. The coatings exhibited superoleophobic behavior against diiodomethane and cooking oil, as well as highly oleophobic behavior against hexadecane. This work demonstrates a simple and efficient route for the fabrication of superamphiphobic surfaces. Additionally, these surfaces are among the first examples of coatings prepared via self-assembly techniques that exhibited high repellency against hexadecane. These materials could have potential in various applications that require protection of a surface against wetting by either water or oils. / Thesis (Master, Chemistry) -- Queen's University, 2013-10-18 12:36:39.039
